[Bug 110636] Re: hdparm - cannot set dma on IDE hard drive that works via pata

[alih]

Maybe from developers' viewpoint it's a feature, but from my viewpoint it's still a bug. I want to turn DMA *off*. Welcome to Asus A6R, the laptop from hell. Depending on DMA mode of the DVD drive and whether you're running X or not, either your USB controller or the network card might get frozen. The solution is to turn off DVD's DMA when you don't need it. Now if libata intentionally doesn't support that then I'm intentionally not using libata. By the way, libata also prevents hibernation on that laptop, so that's the second reason not to use it. The third reason is xine-check.
I would describe the bug as "giving the user not enough information about the choice of libata, its consequences, and the ways to fall back".
